WebThe molar masses of CH 4, SiH 4, GeH 4, and SnH 4 are approximately 16 g/mol, 32 g/mol, 77 g/mol, and 123 g/mol, respectively. Therefore, CH 4 is expected to have the lowest boiling point and SnH 4 the highest boiling point. The ordering from lowest to highest boiling point is expected to be CH 4 < SiH 4 < GeH 4 < SnH 4 .

WebBond energy is a measure of its strength. The higher is the bond energy, the more work you have to do to break it. The bond energy increases with its multiplicity. A double bond between the same pair of atoms will have a higher energy than the analogous single bond.
